A romantic holiday in Barbados may have seemed like the perfect way for Simon Cowell and his fiancé Mezhgan Hussainy - finally reunited after some time apart - to smooth over any rough patches in their relationship.

But it seems things haven't gone to plan for the couple.

The sticking point seems to be that the couple aren't alone on their getaway. A group of Simon's friends, including his ex girlfriend Sinitta, are also there.

Five days later Mezhgan arrived. And, according to the Daily Mail, she has requested that Sinitta not be invited onto Simon's yacht for New Year's Eve – giving them a romantic night alone.

A few hours after the X Factor producer's American girlfriend arrived, Sinitta tweeted: "If this was Dynasty, I seem to have found myself cast as Alexis! Against type but a great role. So lights, camera - action!"
